Q if this is its orbital path the data is either wrong or they are lying as this is the first time we have seen it so where did it come from?
C/2019 Y4 (ATLAS)
Classification: Comet SPK-ID: 1003655
For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.
